Radiography Testing (RT) is the oldest Non-destructive testing method which reveal internal discontinuities and features. Most conventional RT techniques done by taking radiography exposures by either a Gamma ray source (Iridium 192) or an X-ray machine (directional or Panaromic with Max KV rating of 300 KV) by recorder permanent images on the photographic films and interpreting on differential absorption. Radiography testing is employed commonly for welds of different industries as Process, Power generator, Petrochemicals etc. for various thickness and alloy content on dense or light alloys.
